CVE-2026-50453

CVE-2026-50453 affects the Windows USB Audio Class driver (usbaudio.sys). It is an out-of-bounds read vulnerability that may disclose information and requires physical access (attack vector: physical, base CVSS 6.1). Root cause: memory read past bounds. Impact: information disclosure with a physi...

kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture USB audio subsystem. An inconsistency in how USB audio playback and capture streams are handled can lead to an out-of-bounds write to a memory buffer. This can result in a system crash, causing a denial of service for a...
